Good running pack for big breasted women?

I am looking for suggestions for a good running hydration pack for big breasted women. I have a problem with my packs riding up to my neck because the straps above the breast get pushed upward with the bouncing of my breasts. Most packs are not made with big breasts in mind.

Have you tried any of the ones that are made for women (sorry, I have my running backpack at the office, you could put a bladder in it, and I'm trying to remember the name...I'll either remember this weekend or look on Monday). The clavicle clip is higher than on some others. But I also rely on really strapping my boobs down. Which bra do you use?

I don't know, I guess your talking about those Camel backs that are worn more like back pack? I wear my Hydration belts on my waist/hips and have the individual bottles which don't interfere with my Bra or boobs. Sounds like a individual Bra issue which RobinDC mentioned?

Since I have big breasts, I am very conscience of having a good bra that keeps things from bouncing. The problem is that most packs have a strap above the breasts that simply ride up all the time making long runs uncomfortable. I have made my own modifications with velcro straps to go under the breasts. This has helped a lot. I was just hoping that someone else had found a good pack that worked well with big breasts.
